Apologies if this question has already been asked. I looked but couldn't find a topic describing my issue. I have only just installed PMS and so far am very impressed. My problem came when trying to play back a 720P video file encoded as H264 and with a .mkv file extension. My PC runs Windows 7 with an AMD Phenom 2.1Ghz and 2 Gb of RAM (I know it's a bit memory light, but one of my sticks just died). The video plays back through my PS3 just fine and initially the audio is fine. After a minute or so the audio then becomes very slow, like a cassette tape running at 1/4 speed. Is this just a setting or do I need to replace my bad memory to achieve normal playback? Other files have played back without any problems.
I am having this issue as well and disabling the AV synth does not work in M encoder, I can get some files to play fine via TSMUXER but not M encoder most of the time its annoying as it will play no problem in LPCM 2 channel but i want 5.1, most files will start fine and then after about 1 min or the intro from last week the audio goes slow.
The weird thing is that all files play perfectly when being streamed to my OPPO BR player but not the PS3
